Application filed May 13, 1898. Serial No. 680,617. (No specimens.)

To @U whom it 711 011, concern:

Be it known that I, EUGEN WAGNER, sculptor, a subject of the King of Prussia, Emperor of (ierlnanymesiding at Oharl0ttenburg,Kingdom of Prussia, Empire of Germany, have made a certain new and useful Invention Relating to the Manufacture of Thin Portable Plates, Printed with Pictures, of Polishable Limestone, of which the following is a speciplates thus prepared can be used for a great many purposes-for instance, for congratulation, birthday, or New-Year cards, keepsakes, wall-p'ictures, transparent pictures, and for imitation of Delft painting. Especially for the latter purpose the new thing has the advantage of being of a most beautiful efiect, because of the crystals contained in the stone and the possibility of producing dead and polished or shining surfaces on the picture without detriment to the efi'ect of the colors.

What I claim as my invention, and desire to secure by Letters Patent, is- Thin portable plates of elastic, polishable limestone, on the front surface provided with pictures produced by ordinary, or heliographical printing with colors which are so transparent as to let the structure or grain of the stone shine through, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EUeE WAGNER.
